'Application led September 2.9, 1927. Serial No.`222,856.

This invention relates to siphons and more particularly to a Siphon adapted to be actu' ated by steanioso that water will be drawn through the Siphon and therebyallow the Siphon to be employed to remove water from a boat, caisson, barge or the like.

, One object of the invention is to so forni the Siphon that steam passing through it will create a very strong suction in the water inlet without any reaction from the steam and apply direct pressure to water passing through the outlet So that the Water will be forcibly ejected from the Siphon..

Another object of the invention is to form the Siphon as asingle casting vand thereby produce a Siphon whichfwill be simple in its construction and very strong and durable.

Another object of the invention is to provide a Siphon which may be employed when dredging a river bed and to prevent .danger of clogging the Siphon by having the entire inside construction ofthe same diameter.

The* invention is illustrated in the accompanying drawing, wherein Figure 1 is a longitudinal sectional view through the Siphon, and

Fig. 2 is a transverse sectional view taken on the line 2-2 of Fig. 1.

'Ihe Siphon is formed as a single casting and consists of a body portion 1 enlarged intermediate its length, as shown at 2, and having its upper end portion formed with a Y longitudinally extending bore 3 which communicates with a chamber 4 formed in the enlarged intermediate portion 2 of the body. lThe outer end portion of the bore 3 is threaded, as shownat 5, so that an outlet pipe 6 may be screwed into the outlet end of the body and conduct water sucked through the Siphon to a Suitable place of disposal. The chamber 4 extends circumferentially in the enlarged intermediate portion of the body about a boss 7 which extends upwardly in thechamber and terminates close to the inner end of the outlet passage 3. Its upper end portion is beveled, as shown at 8, so that steam may pass from the chamber about the boss into the outlet and cause a'strong suction to take place in the passage 9 which-ex.- tends through the body, as shown in Fig. 1, and communicates with the bore or water inlet passage 10 formedaxially through the side arm 11. The side arm which is cast integral with the body vprojects radially therefrom and its' bore or passage 10. 1s threaded, as shown at 12, so that a suction hose or pipe 13 may be secured in the side arm. The-pipel 13 may be of any length de- Sired in order to reach the place from which water is'to be withdrawn. Since the boss which forms' walls for the upper portion of the passage 9 terminates close to the lower orinner endv of the passage 3 and the steam passes at a rapid rate into the passage 3 about the tapered upper end of the boss, a very good suction will be formed through the passage and the water freely sucked through the pipe 13 and passage 9 and caused to pass upwardly through the passage 3 and pipe 6.

In order to admit Steam to the chamber 4, there has been provided a passage 12 which passes through the body at the opposite side thereofI from the side arm 11 and at its lower end communicates with the bore or passage 18 formed axially in the lower end portion 14. of the body. The walls of the passage 13 are threaded, as shown at 15, to receive a pipe 16 leading from a suitable source of steam. The steam after passing from'the pipe 16 into the passage 12 enters the chamber 4 and from this chamber passes into the passage 3 thereby causing a suction in the l passage 9 and bore 10 to cause a column of water to move through the pipe 13 and out oi. the Siphon through the passage 3 and pipe 6. In view of the fact that 'the Siphon is formed as a single casting, it will be simple in its construction and very strong and durable.

Having thus described4 the invention, I claim: 5' v 1. A Siphon comprising a hollow body open at its upper and lower `ends and having its intermediate portion enlarged to provide va chamberhaving an outlet `leading from its upper end and a reduced inlet communicating with its lower end, and a hollow side arm extending transversely from the lower portion of the enlarged intermediate portion of Said body and having an elbow at its inner end extending upwardl in the chamber land terminating adjacent t e upper end thereotl in alinement with the outlet.

2. A Siphon comprising a body increased in diameter intermediate its ends and formed with aside arm adjacent the lower end of the enlarged portion, the enlarged portion hav-v -ing an annular chamber formed in its upper portion about a central boss and the Side arm having a bore extending axially therethrough and upwardly in the body through the boss, the upper end portion of the body having a 'bore extending axially therethrough' and communicating with thel chamberabove the boss to provide un outlet and the chamber having the uppei` portion of its Walls converging upwardly and gradually merging into the outlet, and the lower end of the body having :1 bore extending axially through the moonen same and communicating with ai passage ei;d tending upwardly through the body at the opposite side of the boss from the side exle'n- 10 Sion and opening into theehainber.
